2015-10-19qga: guest exec functionalityYuri Pudgorodskiy
Guest-exec rewritten in platform-independent style with glib spawn. Child process is spawn asynchronously and exit status can later be picked up by guest-exec-status command. stdin/stdout/stderr of the child now is redirected to /dev/null Later we will add ability to specify stdin in guest-exec command and to get collected stdout/stderr with guest-exec-status.

Add some local guest agent tests, as it is better than nothing, only when CONFIG_POSIX (using unix sockets). With the QGA_TEST_SIDE_EFFECTING environment variable, it will include tests with side effects, such as freezing/thawing the FS or changing the time.

2015-10-19qga: Use g_new() & friends where that makes obvious senseMarkus Armbruster
g_new(T, n) is neater than g_malloc(sizeof(T) * n). It's also safer, for two reasons. One, it catches multiplication overflowing size_t. Two, it returns T * rather than void *, which lets the compiler catch more type errors. This commit only touches allocations with size arguments of the form sizeof(T).

2015-10-19build: qemu-ga: add 'qemu-ga' build target for w32Michael Roth
Currently POSIX builds rely on 'qemu-ga' target to do qga-only distributable build. On w32, as with most standalone binary targets, we rely on 'qemu-ga.exe' target. Unlike with POSIX, qemu-ga for w32 has a number of related targets such as VSS DLL and MSI package. We can do the full distributable qga-only build on w32 with: make qemu-ga.exe or: make msi To make that work, we tie VSS dependencies onto qemu-ga.exe. However, in reality the DLL isn't part of the binary, so we use a filter to pull them out of the LINK recipe, which attempts to link against prereqs for binary targets. Additionally, it could be argued that VSS is a separate distributable, and shouldn't be implied by qemu-ga.exe binary target. To avoid this, we can tie the VSS dependencies only to the 'msi' target, but that would make it impossible to do a qga-only build of the w32 distributable without building the 'msi' package, which was supported in the past. An alternative approach is to add a new target to build the whole distributable. w32 allows us to use the same build target we use on POSIX, 'qemu-ga', since the current binary-only target on w32 is 'qemu-ga.exe'. To further simplify the build, we also make 'qemu-ga' build the MSI package if the appropriate ./configure options are set, making the full qga-only build the same on both POSIX and w32: `make qemu-ga` Cc: Paolo Bonzini <pbonzini@redhat.com> Cc: Marc-André Lureau <marcandre.lureau@redhat.com> Signed-off-by: Michael Roth <mdroth@linux.vnet.ibm.com>

CONFIG_LINUX_AIO is an implementation detail of raw-posix.c. Don't mention CONFIG_LINUX_AIO in blockdev.c. Let block drivers decide what to do with BDRV_O_NATIVE_AIO. They may print an error if it is unsupported. Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
